Original Abstract

This paper deals with the determination of k-value and activity index for ground granulated blast furnace slag (GGBFS). The aim of this paper is to determine the activity index and k value for different CEM I cement substitutes with ground granulated blast furnace slag. determination of the k-value is based on the relationship of the water/cement ratio and the compressive strength of concrete with GGBFS. The next goal is to create a mathematical function that describes the development of compressive strength depending on the age of the cement mortar or concrete and the amount of cement replacement with GGBFS. Based on the achieved compressive strengths were designed compressive strength function for concrete and cement mortar with high coefficient of determination (above 0.9). Furthermore, k-values were determined for different ages of concrete and replacement of cement with finely ground slag. These k-values increase as the age of the concrete increases.
